It's all about the OVF for me. I haven't had a chance yet to try the latest greatest EVFs (I think those would be the ones in the new Olympus EM-10 and the Fuji XT 1),

E-M1, not non-existing "EM-10" or even E-M10.

Sorry, I can never get the dashes in the right place on the tablet keyboard. I thought the new small Olympus was supposed to have the latest EVF, but if the one on the flagship is better, that only makes sense. Anyway, I haven't tried either of the Olys so I am reserving judgement.

No, E-M10 has the 2 y/o EVF from E-M5.

but up to this point I can easily tell the difference between watching a small TV or screen and actually looking out at the real world through the big hole in the front.

And that is a good thing. The whole in the front cannot show you where you have overexposed or underexposed or botched ISO or WB, for example.

No it's not. That interactive view of the real world is worth the trouble of bracketing my exposures, to me at least.
